Method Detail

getActivationCondition

@Nonnull
public com.google.common.base.Predicate<ProfileRequestContext> getActivationCondition()

Specified by:

getActivationCondition in interface AttributeEncoder<AttributeType extends SAMLObject>

setActivationCondition

public void setActivationCondition(@Nonnull
                          com.google.common.base.Predicate<ProfileRequestContext> condition)

Set the activation condition for this encoder.

Parameters:

condition - condition to set

getName

@NonnullAfterInit
public final String getName()

Get the name of the attribute.

Returns:

name of the attribute

setName

public void setName(@Nonnull@NotEmpty
           String attributeName)

Set the name of the attribute.

Parameters:

attributeName - name of the attribute

encodeType

public boolean encodeType()

Get whether to encode type information.

Defaults to 'true'

Returns:

true iff type information should be encoded

setEncodeType

public void setEncodeType(boolean flag)

Set whether to encode type information.

Parameters:

flag - flag to set

doInitialize

protected void doInitialize()
                     throws ComponentInitializationException

Overrides:

doInitialize in class AbstractInitializableComponent

Throws:

ComponentInitializationException

encode

@Nonnull
public AttributeType encode(@Nonnull
                           IdPAttribute attribute)
                                        throws AttributeEncodingException

Specified by:

encode in interface AttributeEncoder<AttributeType extends SAMLObject>

Throws:

AttributeEncodingException

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

canEncodeValue

protected abstract boolean canEncodeValue(@Nonnull
                     IdPAttribute idpAttribute,
                     @Nonnull
                     IdPAttributeValue value)

Checks if the given value can be handled by the encoder. In many cases this is simply a check to see if the given object is of the right type.

Parameters:

idpAttribute - the attribute being encoded, never null

value - the value to check, never null

Returns:

true if the encoder can encoder this value, false if not

encodeValue

@Nullable
protected abstract XMLObject encodeValue(@Nonnull
                             IdPAttribute idpAttribute,
                             @Nonnull

                                  throws AttributeEncodingException

Encodes an attribute value in to a SAML attribute value element.

Parameters:

idpAttribute - the attribute being encoded, never null

value - the value to encoder, never null

Returns:

the attribute value or null if the resulting attribute value would be empty

Throws:

AttributeEncodingException - thrown if there is a problem encoding the attribute value

buildAttribute

@Nonnull
protected abstract AttributeType buildAttribute(@Nonnull
                                   IdPAttribute idpAttribute,

Builds a SAML attribute element from the given attribute values.

Parameters:

idpAttribute - the attribute being encoded, never null

attributeValues - the encoded values for the attribute, never null or containing null elements

Returns:

the SAML attribute element

Throws:

AttributeEncodingException - thrown if there is a problem constructing the SAML attribute
